Reduced Dispersion Duplex DQPSK Radio-Over-Fiber Communications Using Single-Laser-Based Multiple Side-Bands
Reduced Dispersion Duplex DQPSK Radio-Over-Fiber Communications Using Single-Laser-Based Multiple Side-Bands
Multiple side-bands are generated from a single laser diode with the aid of optical carrier suppression, which facilitates the transmission of reduced-rate parallel streams mapped to the side-bands. As a benefit, all the signal processing tasks including demultiplexing of a high data rate signal into multiple low data rate signals can be performed at the central unit. The technique can also be useful in reducing the effect of dispersion in case of high frequency Radio Over Fiber (ROF) communications by transmitting a single high data rate signal as multiple low data rate signals using the side-bands generated. We demonstrate the duplex transmission of a bit-rate of 768 Mbit/s over a 50 km fiber using three side-bands in each direction. The three side-band aided system has a BER performance which is close to that of the idealized benchmarker operating in a back-to-back mode.

Abstract
Multiple side-bands are generated from a single laser diode with the aid of optical carrier suppression, which facilitates the transmission of reduced-rate parallel streams mapped to the side-bands. As a benefit, all the signal processing tasks including demultiplexing of a high data rate signal into multiple low data rate signals can be performed at the central unit. The technique can also be useful in reducing the effect of dispersion in case of high frequency Radio Over Fiber (ROF) communications by transmitting a single high data rate signal as multiple low data rate signals using the side-bands generated. We demonstrate the duplex transmission of a bit-rate of 768 Mbit/s over a 50 km fiber using three side-bands in each direction. The three side-band aided system has a BER performance which is close to that of the idealized benchmarker operating in a back-to-back mode.
